I have a 2010 Smith Maze helmet, I don't think much has changed. The muffs are removable which is nice. Mine didn't come with the pads that had the zipper for sound, but I actually e-mailed them last year asking if I could buy a set of the muffs with the zipper and they sent me a pair for free!

The helmet fits well, is warm, which is why it's nice to have those muffs come off come spring and has held up well since I bought it. The only thing I don't like is that the goggle holder on the back opens on the bottom instead of the top. Damn gravity.

I use my regular panasonic earbuds in the helmet and the sound it just fine.
